CQOLING BOX.

Application tiled March 30,1925. Serial lo. 19,398.

in a compartment structure surrounded vwith insulating materlal and having circulating therein a cooling medium, and having disposed within certain compartments surrounded by the cooling circulating medium means for controlling the temperatures toV be developed or maintained within the compartments by 'regulating automatically, the volume of the cooling medium to be circulated therearound.

A further object of my invention is to automatically regulate, by a temperature thermostatic control, through the medium of a three way valve, the volume of cooling circulating mediuml passing around the compartments to be cooled and therefore control the temperature, of the compartments, within certain ranges of temperature, withoutchanging the temperature of the circulating cooling medium.- l f A further object of my invention, is to control the temperature of .certain of the compartments, within the box, within certain and 'limited ranges of temperature; due to the distance of the compartments from the automatic regulating control device.

A further object of my invention consists: inl causing the circulating cooling operating y h: stantlal coating offinsulated materiaLQa, as

.medium, as brine, to follow a circuitous pat in and around certain of the compartments whose temperature is to be'regulated and in so doing, to create and maintain different temperatures, in the diierent compartments, .along the dhannelof the cooling circulating operating medium.

A further objectof myinvention consists of forming a box of lowl heat conductivity, the placing of a vattherein of a number o "a layer .of substantial. thickness of insulating mate- ;rials betweenA the inner walls of thel box and the outer lwalls of the vat, and the placing within the vat of a number of'diierent compartments adapted to the circulating therearound of a cooling circulating medium, as brine, and a closedcircuit of piping adapted to circulate the cooling medium from the refrigerating machine through the box and back to therefrigerating machine, and automatic means within the circuit regulating the channel of flow of the cooling medium, and lidded openings to each coml partment Within the box.

'I With these and incidental objects in view, the invention consists in certainnovel .-features of construction and combination of parts, the essential elements of whichI are set forth in the appended claims andto a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part .l

of this specification.

In the drawings,- Fig. 1 is a plan view of my new and-improved cooling box.

Fig. 2 is a front in section, of the Fig. 1. Fig. 3 is side elevation, partially an enlarged sectional `view taken `outline 3-K-3 of Fig. 2, looking in the direction indicated.

l* 1g. 4 is'an enlarged', sectional, plan view of the mechanism shown in Fig. 2, taken on.

line 41-4 of Fig. V2, looking in the ldirection indicated.

mechanism shown 1nA v Fig. 5 is aj cross section View taken on line 5 5' of Fig. 4, looking in' the direction` indicated.

Like reference charactersV refer to -like parts throughout the several views. 4'

, 1 is the main box structure made oflow heat conducting. material, as wood, having an inner vat compartment 2 disposed therein and between the two a heavy .and subcork, or other suitable material to maintain therein the/low temperatures thus created.'

f ment 5, located therein which is maintained by the wall -structure of the' same. 'It is intended by my construction that the lowest 'temperatures to be maintained within this maintained within the compartment'.` 5, and, therefore, the cooling. circulating medium, as brine, shall be taken directly from the liquid cooling box willL be surrounding the expansion chamber of the i'efrigeratin device and deposited therearo'und. A ba e plate 8 disposed within the space 4, will cause a circulation of the medium around the side walls and bottom Walls of this compartment and the same will leave the compartment through the vpipe 9; disposed within this pipe is a three Way valve 10, having a valve' arm 11, disposed thereon and attached to the valve stem of the valve to which a, heat regulating thermostat piston 12 is attached, the thermostatl 13, is disposed within the wall structure of the compartment land which is adapted to being set at the temperatures required to be maintained within a compartment of the device. The temperature of the thermostat is determined by the temperature of the cooling circulating medium within the space 15. An inlet pipe 15a passes through the wall of the compartment and permlts the cooling medium to surround the thermostat. An inlet pipe 14, leads from the three way valve and, therefore, from the circulating pip/e 9, and discharges the cooling circulating medium,

within the space 15. The battle 16, causes the cooling circulating medium to surround the compartment 17, and thence in the direction of the arrow to the tank 18, caused by the battle 19 located therein, thence around the compartment 20, in the direction indicated, created by the balie 21,and thence around the compartment 22, caused by baille 23, and thence around the compartment 24, caused by the baffle 25, and thence back into the outlet pipe 26, through the outlet connection 27, through ythe Wall of the cooling box. It willy thus be apparent so long as the circulation is kept up and some heat escapes that the compartment 17, "will be somewhat colder than compartment .18, and compartment 18 somewhat colder than compartment 20, andthat compartment 2S will likewise be somewhat colder than compartment 24, because of the leakages of the temperature in the cooling medium, as the same passes from compartment to compartaient.A 1f the thermostat 13, is set for a certain temperature to be maintained within the cooling circulating medium in and around the first compartment 17, when this temperature is reached, the thermostat will be operated and the valve stem 11, will shut od the inlet three way valve and the cooling circulating medium will pass directly for its outiet through pipe 9, and pipe 26, back to the expanding. tank surrounding the 'expanding chamber of the r-efrigerating machine; butwhen the temperature rises above that required, the valve will be opened and a certain ernennt of the cooling circulating` medium will pass in and around the compartments, as described. 1t will thus be apparent to these skilled in refrigerating matters 'that have created a device adapted to automatically regulate the temperatures to be maintained therein Within certain temperature limits.

While the form of mechanism `herein shown and described is admirably adapted to fulfill the objects primarily stated, it is tobe understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming WithinA the scope of the claims which follow. Y
